Always enable regabig on AMD64, which enables the G register and the X15 zero register. Remove the fallback path. Also remove the regabig GOEXPERIMENT. On AMD64 it is always enabled (this CL). Other architectures already have a G register, except for 386, where there are too few registers and it is unlikely that we will reserve one. (If we really do, we can just add a new experiment).
